Yes, Apple Watch batteries can be replaced, but Apple handles the repair, not you
You cannot replace an Apple Watch battery yourself. The battery is sealed inside the watch case, and opening it requires specialized tools and training. Apple replaces batteries through their official repair service, which costs between $70 and $100 depending on your watch model. The repair takes about one to two weeks, and Apple will send you a replacement watch while yours is being serviced if you pay an extra fee.
If your watch is still under warranty or covered by AppleCare+, battery replacement may be free or cost only $0 to $50. Without coverage, you pay the full repair cost. The battery is considered a wear item — Apple expects it to degrade over time, so damage from normal use is usually covered, but damage from physical impact or liquid exposure is not.
Key Takeaways
- Apple Watch batteries are not user-replaceable and must be serviced by Apple or an authorized repair provider.
- Battery replacement costs $70 to $100 without coverage, or less if you have AppleCare+ or an active warranty.
- The repair process takes one to two weeks, though you can request a loaner watch for an additional fee.
- You can start a repair request through the Apple Support app, at an Apple Store, or by calling Apple Support directly.
How to request a battery replacement through Apple
Open the Apple Support app on your iPhone or iPad and search for "battery service" or "Apple Watch repair." Select your watch model and describe the battery problem — for example, "battery drains quickly" or "won't hold a charge." The app will show you the repair cost and available service options.
You can also visit an Apple Store in person and ask the Genius Bar to run a battery diagnostic. They can tell you on the spot whether the battery needs replacement and give you a quote. If you prefer not to visit a store, call Apple Support at 1-800-MY-APPLE and they will arrange a mail-in repair. Apple will email you a prepaid shipping label, and you send your watch to their repair center.
Before sending your watch in, back up your data through the Apple Watch app on your iPhone. Unpair the watch from your iPhone by opening the Apple Watch app, going to the My Watch tab, selecting your watch at the top, and tapping the information icon, then "Unpair Apple Watch." This erases the watch and removes it from your account so the repair center can service it without your personal data on it.
What AppleCare+ covers for battery replacement
AppleCare+ is Apple's extended protection plan for Apple Watch. It costs $79 for most models and covers accidental damage, hardware failures, and battery replacement. With AppleCare+, battery replacement is free if the battery capacity has dropped below 80 percent of its original capacity. If you damage the watch accidentally and the battery needs replacement as part of that repair, you pay a $79 service fee instead of the full repair cost.
AppleCare+ lasts two years from the date you purchase it. You can check whether your watch has active coverage by opening the Apple Support app, tapping the menu icon, selecting "My Support," and looking for your watch in the list. If you do not have AppleCare+ and your watch is still within one year of purchase, the standard one-year warranty covers battery replacement if the battery is defective — but not if it simply degraded from normal use.
How long battery replacement takes
Mail-in repair through Apple typically takes seven to fourteen business days from the moment Apple receives your watch. This does not include shipping time to Apple's repair center. You can expect the entire process — packing, shipping, repair, and return shipping — to take two to three weeks.
If you need your watch sooner, visit an Apple Store and ask about same-day or next-day service. Not all stores offer this, and it depends on parts availability and current repair volume. Some Apple Stores can replace the battery while you wait if they have the part in stock, though this is less common than mail-in service.
If you cannot be without your watch during the repair, Apple offers a loaner program. When you start a repair through the Apple Support app or at an Apple Store, you can request a loaner watch for an additional $29 to $49. Apple will send you a replacement watch to use while yours is being repaired, and you return it when you get your original watch back.
Third-party repair options and what to know about them
Some independent repair shops and electronics retailers offer Apple Watch battery replacement for less than Apple charges — typically $40 to $60. These shops are not authorized by Apple, which means the repair may void your warranty if you still have one active. Opening the watch case can also damage the water resistance seal, so the watch may no longer be waterproof after a third-party repair.
If you choose a third-party repair, ask the shop whether they can may provide water resistance after the repair and whether they offer a warranty on their work. Get the quote in writing before you leave the watch with them. Some shops will replace just the battery, while others may charge extra to reseal the watch properly.
If your watch is out of warranty and you do not have AppleCare+, a third-party repair can save you money upfront. However, if something goes wrong during the repair or the watch stops working properly afterward, you have no recourse with Apple — they will not service a watch that has been opened by an unauthorized repair shop.
Signs your Apple Watch battery needs replacement
The most obvious sign is rapid battery drain. If your watch used to last a full day on a single charge and now dies by mid-afternoon, the battery is likely degraded. Another sign is if the watch shuts down unexpectedly even when the battery percentage shows 20 or 30 percent remaining — this means the battery cannot deliver power consistently anymore.
You can check your battery health directly on the watch. Open Settings, scroll to Battery, and look at the Battery Health section. If it shows below 80 percent, Apple considers the battery degraded. A battery at 50 percent health or lower will definitely need replacement soon. If you have AppleCare+, you can get it replaced for free at this point.
Some users notice the watch running slower or apps taking longer to open as the battery ages. This is not always a battery problem — it can also be a software issue — but combined with rapid drain, it suggests the battery is the culprit. If you are unsure, the Apple Support app or a Genius Bar appointment can run a diagnostic to confirm.
What happens to your data during battery replacement
When you unpair your watch before sending it in for repair, all your data — activity rings, workouts, health data, and apps — is backed up to your iPhone through iCloud. After Apple replaces the battery and returns your watch, you pair it with your iPhone again, and all your data syncs back automatically. You will not lose anything.
The repair center erases the watch during the repair process to ensure your personal information is not on the device when it leaves their facility. This is why unpairing before you send it in is important — it ensures the backup is complete and up to date. When you pair the watch again after repair, the setup process asks whether you want to restore from backup, and you select yes.
Frequently Asked Questions
Can I replace the battery myself with a kit from online?
No. Apple Watch batteries are soldered to the circuit board and require specialized equipment to replace safely. DIY kits can damage the watch permanently, break the water resistance seal, or create a safety hazard. The cost of a failed DIY repair often exceeds the cost of having Apple do it.
Will Apple replace the battery if it is swollen or bulging?
Yes, and this is actually a priority repair because a swollen battery is a safety risk. Contact Apple immediately if your watch battery is visibly swollen. Do not attempt to use the watch. Apple will prioritize the repair and may expedite it because a damaged battery can overheat.
What if my watch is older than five years?
Apple may decline to repair very old models if parts are no longer available. Call Apple Support with your watch model and serial number, and they can tell you whether repair is possible. If Apple cannot repair it, a third-party shop may still be able to, though options are more limited.
Do I have to go to an Apple Store, or can I mail it in?
You can do either. Mail-in repair is free and takes two to three weeks total. Apple Store visits are faster if same-day service is available, but not all locations offer it. You can start the process through the Apple Support app and choose which option works best for you.
Will the battery replacement fix my watch if it is also running slowly?
Maybe. If the slowness is caused by a failing battery that cannot deliver power consistently, replacing the battery will fix it. If the slowness is a software issue, the battery replacement will not help. The Apple Support app or Genius Bar can run diagnostics to determine the cause before you pay for repair.
